The Tank Lords
by David Drake

COLONEL ALOIS HAMMER: He welded five thousand individual killers into a weapon more deadly than any other in the human universe. When a planetary government faces unfriendly natives, guerrilla insurgents, or ruthless terrorists, they do the only thing that might save them— they hire Hammer's Slammers, the toughest, meanest bunch of mercs who ever wrecked a world for pay. Known throughout the galaxy for their cold, ruthless ferocity, the men of Colonel Hammer's indomitable armored brigade routinely accept impossible missions. Again and again, they go up against overwhelming forces, or fight a two-front war against ferocious opposition, all without atomizing their civilian employers. Can they keep doing it? Not if they abide by the rules of civilized warfare...but nobody ever said the Hammers were nice. Even when their chances are not good—those who oppose them have no chance at all!
